Original Department of Energy caption:
"External view of the 40-KW PC-18 Pilot Power Plant.
"Onsite fuel cell power plants contain three major sub-systems, or sections.
In the fuel processing section, natural gas is converted to a hydrogen-rich fuel. It is then
fed into the power section, where the hydrogen is electro-chemically reacted with oxygen
from the air to produce direct current (DC) electricity and by-product heat (in the form
of hot water or steam). In the power conditioning section, the DC electricity is converted
to alternating current (AC) at the appropriate frequency and voltage levels. This 40 KW power
plant, developed by the Team to Advance Research on Gas Energy Transformation (TARGET)
and the United Technologies Corporation (UTC), achieved total efficiencies of up to 80 percent
and paved the way for technical and operational field testing."
